It's a fine song but I'm reasonably certain it isn't news, conveying the news in a meaningful fashion, or newsworthy in its existence. We have tons of music subs, on the other hand. Hell, we even have generic subs.

It's fine that you do so, nobody is really going to much care. I may stop and give you shit for it. That's about the extent of it. In the grand scale of misplacing submissions, that's not very bad. It could be worse, you could have put it in a science or physics sub.
